Birthday Brush

There's an Easter Egg hidden in the Calligraphic Brush Options dialog that was revealed by Deke McClelland in his Real World Adobe Illustrator book. Why is it called an Easter Egg? Because it's a little hidden treat that serves no practical purpose whatsoever. Double-click on any Calligraphic brush to open the options dialog and enter these settings: Angle 5°, Roundness 26%, and Diameter 56 points. Click anywhere in the dialog, and you'll get a birthday surprise. Does the brush actually paint with this special design? No, thus the Easter Egg designation cool but no practical application.
